WINDOW-CLEANERS SAFETY APPLIANGE.

Specification of Letters Patent.

Patented Jan. *7, 1919.,u

Application led June 10, `1918. Serial No. 239,190.

j clare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

the act of cleaning the outside surfaces of the window panes. j

It is an object of my present invention to provide a device for the above described purpose which will be simple in construction, readily attachable tothe window sash and extremely effective for the purpose intended.

Tn the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views:

Figure 1 is a vertical sectional view through a window showing a window cleaner in dotted lines and an appliance mounted on the window sashes which is constructed in accordance with my present invention.

Fig. 2 is a perspective view, partly fragmentary, of the improved appliance.

Fig. 3 is a side elevational view with parts shown in section of the impro-ved clamp shown in place on the bottom rail of the lower sash which is indicated in dotted lines.

Fig. 4 is a view similar to Fig, and showing a slight modification of th; clamp; and j Fig. 5 is a persepctive view of the window cleaners belt.

Referring more particularly to the accompanying drawings, 1 and 2 designate the lower and the upper sashes, respectively,

which are tted for the usual vertical movement in the window frame 3.

The lower stile 4 of the lower sash 1 is arranged to receive a clamp, which is shown more particularly in Fig. 2 wherein the same referably consists of a single length of wire gent upon itself to form the U-shaped arms 5 and 6 connected together lby the bar 7. The two arms 5 and 6 are adapted to be fitted uponthe lower stile 4 in the manner shown in Fig. 1, and aclanipblock is there i after brought up tightly against the outer face of said stile 4 where it is secured `thereagainst in order to hold the arms 5 and `(i tightly in place thereon. This clamp block preferably consists of upper and lower parts 8 and 9, respectively, each having `correspondingly formed semicircular openings 10 and 11 through which the horizontal strandsof the arms 5 and 6 are adapted to passythe walls of the openings 10 and 11 being adapted to frictionally grip said horizontal strands in order to hold the clamp block tightly in the adjusted position against the sti e Threaded bolts 12 and lipass vertically through bolt registering holes provided for this purpose in the parts 8 and 9, there be ing preferably countersunk grooves 14 and 15 in the top of the part 8 which are occupied by the heads of the bolts 12 and 13.

The lower threaded ends of the bolts project below the lower part 9 where they receive nuts 16 and 17 through which the two `parts 8 and 9 of the block are forced together upon the horizontal strands of the arms 5 and 6.

In Fig. 4 I have shown a slight modifica-` tion of the clamp in which the vertically eX- tending free ends 18 of the arms 5 and 6 are arranged to come directly into contact with the outside surfaceof the lower stile 4, while the opposite vertical portions of the arms carry a block 19 through which passes horir zontally an adjustable screw 20 operated by the hand in engagement with a butterfly part 21, and which adjustable screw carries a movable plate 22 into and out of engagement with the `inner face of the stile 4; by which means the clamp is tightly secured thereon. A canvas or other tape 23 of appropriate strength is secured to the clamp preferably by folding one end of the tape 23 about the clamp bar 7 and securing the same to thc body of the tape by several rows of stitching 24. As shown to advantage in Fig. 1, the tape 23 is adapted to be carried vertically upward from the clamp on the inside of the lower sash 1 and to be brought over such lower sash and carried downwardly between the two'sashes 1 and 2 and thence carried about beneath the lower stile of the .upper sash 2.-

T'here are a series of openings 25 made in the tape 23 which are preferably reinforced by metallic eyelets, and on the belt 26 which is worn by the window cleaner shown in dotted lines in Fig. l there is secured a snap hook 27 with which any one of the eyelets 25 is adapted -to engage. The belt 26 is constru-cted in any appropriate manner and is provided with pockets or sockets 28 to receive various tools useful in the trade, such, for instance, as a brush 29, a hammer 80, etc. The belt also forms a support for the receptacle 3l having the hooks 3:2 which fit over the upper edge thereof.

The use of the improved device is aptly illustrated in 'Fig l, where the window cleaner shown in dotted lines and wearing the belt 26 is held securely from falling in his .position on the window ledge by my iniproved appliance. Any one of the eyelets Q5 may be snapped through the hook 27 in accordance with the position assumed or 'the amount of play required by the window cleaner in his operations.

By having the tape 23 pass between the two sashes l and 2 and about, respectively, the upper and lower stiles thereof, the strain is distributed throughout various parts of such tape, and a great deal of strain is taken off the clamp avhich would otherwise directly devolve thereon. The position of the appliance, however, interferes in no way with the movement of the windows or accelzssibility to all parts of the exterior of the fr ass. c From the foregoing description, taken in connection with the drawings, it will be obvious that I have provided a compact device for the purposes intended which admits of rbeing readily rolled up for carriage from window to window, and admits of ready removal and replacement on the several windows.

It is obvious that those skilled in the art may vary the details 0f construction and arrangements of parts without departing from the spirit of my invention, and therefore I do not wishl to be limited to such features except as may be required by the claims.

I claim:

l. A window cleaners safety appliance including a clamp adapted to be attached to one of the window sashes, and a iexible tape attached to said clamp and passing about the lower window sash and transversely of the upper, in combination with a belt worn by the window cleaner and having a hook to which the tape may be attached, substantially as described.

2. An improved window cleaner safety appliance including a clamp having an adjustable means whereby it may be secured to the lower stile of the lower sash in a window frame, a strong flexible tape attached to said clamp and passing transversely of theupiper stile of the lower sash and transversely of the lower stile of the upper sash after passing between such sashes, said tape havinga series of openings therein, in combination with a belt worn by the lwindow cleaner, and a hook carried by suoli belt and adapted to be -engaged by the openings provided in. the tape, substantially as described.

3. In combination with a belt worn by a window cleaner, of a snap hook carried by said belt, a flexible tape having a series of reinforced eyelets therein whereby the tape may be adjustably secured in the snap hook, the tape adapted to pass vertically between the upper and lower sashes of a wind-ow frame and below and above, respectively, the lower and upper stiles of the upper and lower window sashes` and a clamp attached to said flexible tape and having an adjustable block adapted to be fitted against the lower stile of the lower sash whereby the clamp may be held thereon, substantially as described.

4. In combination with a belt worn by a window cleaner, of a snap hook carried by such belt, a clamp made up of a single length of wire bent upon itself to provide spaced apart U-shaped arms adapted to embrace the lower stile of the lower sash, a two-part separable block adapted to frictionally bind on said clamp and to fit tightly against the sash stile to hold the clamp thereon, means for tightening the two parts ofthe block whereby to hold the same in the adjusted position, and a flexible tape secured to the clamp and pass ing between the sashes, the tape having a series of reinforced eyelets for engaging the snap hook whereby the window cleaner may be securely held from falling, substantially as described.

In testimony whereof, I affix my signature.
